Code Description

ICD-10 M46.48 is a billable code used to indicate a diagnosis of discitis, unspecified, sacral and sacrococcygeal region.

Key Diagnostic Point:

Discitis is an inflammatory condition affecting the intervertebral discs, characterized by pain and potential neurological deficits. In the sacral and sacrococcygeal region, discitis can arise from various etiologies, including bacterial infections, autoimmune disorders, or post-surgical complications. Patients may present with localized pain, fever, and neurological symptoms depending on the severity and extent of the inflammation. The sacral region is particularly vulnerable due to its anatomical position and the weight-bearing nature of the pelvis. Diagnosis typically involves imaging studies such as MRI or CT scans, which can reveal disc space narrowing, edema, or abscess formation. Treatment often includes antibiotics for infectious causes, anti-inflammatory medications, and in severe cases, surgical intervention may be necessary to decompress affected neural structures. Understanding the underlying causes, including associations with spondylopathies like ankylosing spondylitis or inflammatory spine conditions, is crucial for effective management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between infectious and non-infectious causes of discitis
  • Need for comprehensive imaging documentation
  • Potential overlap with other spinal conditions
  • Variability in clinical presentation

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify the cause of discitis
  • Lack of imaging reports in the medical record
  • Misclassification of discitis as a different spinal condition

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed surgical notes, imaging results, and post-operative assessments are essential.

Common Clinical Scenarios

Post-surgical discitis following spinal fusion or decompression procedures.

Billing Considerations

Documentation must clearly indicate the surgical history and any complications.

Infectious Disease

Documentation Requirements

Comprehensive lab results, cultures, and response to treatment must be documented.

Common Clinical Scenarios

Discitis due to bacterial infections, particularly in immunocompromised patients.

Billing Considerations

Clear documentation of the infectious etiology and treatment regimen is critical.

Frequently Asked Questions

What is the primary cause of discitis?

Discitis can be caused by infections, autoimmune conditions, or post-surgical complications. Bacterial infections are the most common infectious cause.
